Mineral processing is a process that valuable constituents of an ore are concentrated by means of a physical separation process.
Mineral Processing Experiment and Metallurgical Testing
Lab Introduction
As one of the most important basis of next project design, ‘Mineral Processing Experiment Report’ brings significance of guiding actual production. HOT Mining provides ‘one-stop’ solution for mining and mineral processing and the lab owned by our partner helps us do mineral processing experiment, and we can assure it is much more quality-reliable.
The lab provides a complete set of mineral processing research services for mining development. The lab is fully equipped with a variety of advanced testing and analysis equipment and instruments.
Process
Sample preparation
Receiving ore samples, core samples, slurry samples or liquid samples through a range of processes including, but not limited to, core logging/cutting/photography, sizing, screening, sub-sampling, crushing & grinding, pulverising, de-sliming.
Chemical testing & analysis
Chemical testing & analysis of the material components (ore structure, mineral and types of ore) and chemical properties (elements, the particle size screening, density, ore relative grindability) of crude ore.
Mineral processing experiment
In order to get the optimum conditions of mineral processing, firstly there’s exploratory experiment. After the technical team fully analyzed the physical and chemical properties of the ore samples, combined with a solid theoretical basis and rich practical experience, a preliminary exploration experiment plan was formulated. And then detailed experiment including grinding fineness, reagent dosage, open and closed circuit experiment, is carried out.
Sedimentation experiment
After obtaining the final products, technicians will analyze the recovery rate, and then take sedimentation experiment of concentrate and tailing as references for equipment selection.
Analytical services
Analyzing mineral processing testing with in-house wet chemistry, aqua- regia digestion, titrations, diagnostic gold analysis, AAS (atomic absorption), and TGA (thermogravimetry analysis) analysis.
Experiment result
After finishing all the experiment, the lab will submit a detailed ‘Mineral Pro-cessing Experiment Report’ by summarizing all the experiment processes. In the last part of report, the optimum technological process and technological parameters will also be presented.
Quality management
Internal and external testing: random inspection of the material during the test cycle or Irregular sampling inspection for the sample ore.
Services introduction
The types of experiments HOT can provide are as follows:
1. Mineral processing Experiment
The mineral processing experiment is carried out on a laboratory device or a small experiment instrument, and is generally used only for evaluation of ore deposits.
2. Small Scale Mineral Processing Experiment
For most projects, it can meet the requirements of preliminary design of process and product plan, selection of main process equipment and comparison of design alternatives.
3. Scale-up Continuous Experiment
It can be more reliable to provide reference and guidance for process design, equipment selection. It is suitable for large and medium-sized projects and refractory projects.
4. Semi Commercial Experiment
The purpose of the experiment is to verify the process plan of the laboratory experiment, and to obtain the technical and economic indicators similar to the practical production.
5. Commercial Experiment
The commercial experiment is carried out in a series of local commercial plant established by production or concentrator plant or even the whole process of the experiment, because of its equipment, process, technology and production conditions or the future design is basically the same, so the technical and economic indicators and technical parameters are more reliable than semi commercial experiment.
6. Single technical Experiment
For existing mineral processing plants, when equipment / process / agent / material needs to be replaced / upgraded / modified, a single technical experiment is needed to get technical support.
